To add a second EC2 instance as a worker for specific deployments with your Prefect OSS, you'll want to follow these general steps:
1. Set up the second EC2 instance with the required prerequisites for running Prefect.
2. Create a work pool associated with the type of infrastructure you are using (e.g., ECS if you are using AWS).
3. Start a worker on the second instance and assign it to the created work pool.
4. Configure your deployments to use the created work pool, ensuring they are directed to execute on the second EC2 instance.
Here are the relevant resources to help you with each step:
- For general information on how to use workers and work pools with deployments, check the
Prefect Docs on Workers and Work Pools.
- If you plan to use ECS as your infrastructure, follow the guide on creating a work pool and starting a worker:
ECS Worker in Prefect with AWS. You can start a worker using the command:
shell
prefect worker start --pool <your-work-pool-name>
- Additionally, the
GCP Worker Guide provides an example of setting environment variables and deploying a worker. Even though it is for GCP, the concept can be useful for understanding how to work with workers and environment variables on other cloud providers.
Make sure you update the specific commands and configurations to suit your use-case with AWS EC2 and Prefect OSS.
